Polypropylene Europe Margin Report Methodology 30 September 2015
2
This document is intended to provide methodology support for customers receiving the ICIS Weekly Margin – PP Europe report. THE BUSINESS MODEL The diagram below shows the major method of making polypropylene (PP) in Europe: from naphtha, a product mainly derived from crude oil. Naphtha with steam is fed into the cracker unit where ethylene, propylene and other co-products (butadiene, benzene, etc.) are made. The propylene from the cracker is then further processed (polymerised) in the PP plant to make the PP pellets for sale.
THE MARGIN CALCULATION
Margin measure provides assessment of the ex-works cash margin obtained
for the product over raw material costs and key variable manufacturing costs,
such as power, steam, catalysts and chemicals. This measure can also be termed
as a variable margin, contribution or benefit.
It represents a cash margin measure available for supporting the direct and
allocated fixed manufacturing costs, working capital, taxes, royalties, corporate
costs, debt service costs, capital costs and owner’s returns from the business.
This margin measure provides simple signals on the direction of business
margins, as dictated by the environment alone, thus informing market positioning
by sellers, buyers and traders.

ICIS chooses not to model beyond raw material costs and key variable
manufacturing costs as this ceases to be generic to the integrated industry and
highly specific to individual business operations, their site structure, location,
ownership and financial structures. Such detail would not fairly reflect or be
applicable in a wider industry context. It may also be more subjective, open to
fair challenges and not feasible to reference in commercial discussions.
Plant manufacturing and feedstock yield model data have been provided by
Linde Engineering, a division of Linde AG. Linde Engineering (www.linde-
engineering.com) is a leading international chemical plant designer, process
engineering, procurement and construction contractor. It has extensive
experience in steam cracker, PDH and PP plant design.
The process model is generic and not referenced to any individual operation,
so that the contribution measure is only indicative. It can be most valuably
referenced in index and step change terms as opposed to absolute value terms.
Naphtha feedstock has been chosen as this represents the most commonly
used feedstock for ethylene and propylene manufacture in Europe. As such, the
cost model is broadly applicable to the majority of the European commodity
PP business.
Margin measure from the cracker is calculated on a ‘per tonne of olefin’ basis
i.e. the margin achieved when producing one tonne of ethylene and propylene.
A combined olefin analysis is used because ethylene is the primary product
from the cracker.
Ex-works product price assessments are linked to ICIS pricing quotations for
large volume commodity products with netbacks assessed using typical logistic
cost assessments.
The PP grade referenced in the ICIS PP Europe Margin report is the PP
homopolymer injection moulding grade. This generally represents large-volume
commodity grades in the PP market.
The ICIS domestic FD EU quote is referenced as this is broadly representative of the entire west European market.

1The model assumes 2.115 tonnes of naphtha are required to produce 1 tonne of olefin (ethylene and propylene) and 1.01 tonnes of propylene are required to produce 1 tonne of PP. The average net naphtha price (including freight costs) for 2008 was $799/tonne (with an average $:€ conversion rate of 1.47). 2Co-product sales include credits for butadiene, benzene, raffinate-1, pygas and a fuel export balance. Since the cracker margin is based on 1 tonne of olefin (ethylene and propylene) produced, the figure also allows for the difference in net price between ethylene and propylene on transfer to the PP unit.
3The model assumes 1.01 tonnes of propylene are required to produce 1 tonne of PP.
4Includes power and catalysts/chemicals for the PP.
5The model assumes 1.16 tonnes of propane are required to produce 1 tonne of propylene and 1.01 tonnes of propylene are required to produce 1 tonne of PP. The average net propane price (including freight costs) for 2008 was $746/tonne (with an average $:€ conversion rate of 1.47). DIFFERENCE BETWEEN NON-INTEGRATED AND INTEGRATED
Non-integrated or standalone: market participant involved with PP production
only. The business model is to buy propylene, convert it into PP resin and sell
the PP. Our margin model assumption is that the plants are co-located (with
the exception of the buy spot propylene sell domestic PP model) and that the
propylene is transferred at an FOB value. This business model is applicable to
just under half the manufacturing facilities in Europe.
Integrated: market participant involved with both propylene and PP production.
There are two business models. The first is to buy naphtha feedstock, process
it into ethylene, propylene and cracker co-products, convert the propylene
into PP, and sell both the PP, ethylene and cracker co-products. The second
business model is to buy propane feedstock, dehydrogenate it into propylene,
convert the propylene into PP and sell the PP resin. These integrated business
models are applicable to over half of the manufacturing facilities in Europe.
WHY INTEGRATED ANALYSIS
Most west European PP plants (approximately 60% by capacity) are integrated
back to cracker or PDH sources of propylene. This may be co-located and/or
connected by pipeline and with common equity ownership across both assets
6
in the supply chain, that is, the economic boundaries for the majority of the
industry producers are bigger than a standalone polymer unit.
The margin is therefore measured across the supply chain from cracker feedstock
(naphtha) through to PP or PDH feedstock (propane) through to PP and cracker
coproducts.
This analysis demonstrates the volatility of the business and the influence of
price floors that can lead to an uneconomic integrated margin, and generally
forcing a reduction in supply.
WHY NON-INTEGRATED ANALYSIS
Approximately 40% (by capacity) of the western European PP plants are
considered as standalone or non-integrated.
Standalone analysis considers the polymer unit in isolation, which may be useful
for understanding marginal opportunities where optimisation processes could
result in propylene being preferentially used for other propylene derivative
products. However, analysis of standalone historical data does show lower
margins, which may not justify fresh business investment to meet growing
market demands.
MODEL YIELD PATTERN AND CALCULATION Plant manufacturing data relates to the variable cost components of the chemical unit operations. Yield pattern data relates to the overall material balance of the cracker unit, for example for 1.0 tonne of ethylene and propylene produced, a cracker requires 2.1 tonnes of naphtha feedstock, and will produce other co-products (butadiene, benzene, etc.) of 0.7 tonnes. A PDH unit will require 1.16 tonnes of propane feedstock, and will make 1.0 tonnes of polypropylene with no other co-products. The plant manufacturing and feedstock yield model data have been provided by Linde Engineering, a division of Linde AG. The exact yield pattern used cannot be published in an unrestricted document such as this methodology statement. However, for PP Europe Margin report subscribers with a specific requirement to see this data, it can be shared on a case-by-case basis. Please contact the Global ICIS Customer Support Centre if this data is required.

The methodology associated with each ICIS pricing individual pricing quotation referenced above can be found on the ICIS Compliance and Methodology website.
In addition to the above pricing inputs, ICIS pricing uses the $/€ mid-market exchange rate on the date of the report publication issued at 16:00 GMT/UTC by XE (www.xe.com). Mid-market rates are derived from the mid-points between the buy and sell rates of large-value transactions in the global currency markets. A key objective of the calculation procedure is to provide a weekly summary that is most strongly aligned to the reported market price positions on the date of publication. Where ICIS price quotations are not available for individual weeks due to public holidays, then prior week data is carried forward for the specific purpose of populating the model and preventing model inconsistency. This form of data interpolation is inferring some limited data points that may not be market derived, and customers should be aware of this assumption.

All data in the ICIS Weekly Margin – PP Europe report is denominated in euros unless specifically indicated otherwise. LONGER RANGE VIEWS: SPOT vs. CONTRACT MARGIN (INTEGRATED NAPHTHA) This provides a weekly comparison of the calculated margin for spot-based PP sales minus contract-based sales. This switch of ICIS pricing reference is also considered for the naphtha cracker products, so the analysis is deeper than a simple comparison of spot versus contract PP price netbacks. When this differential provides a positive numerical output, this implies that spot-based PP sales derive a higher margin for an integrated producer than contract-based sales. Similarly, when this differential provides a negative numerical output, this implies that spot-based PP sales derive a lower margin for an integrated producer than contract-based sales. For the avoidance of any doubt, the basis on which ICIS pricing data is utilised for each of these respective models is summarised in the table below. For more detailed information about these quotations, please refer to the assessment inputs section above.

SPOT vs. CONTRACT MARGIN (STANDALONE) This provides a weekly comparison of the calculated margin for spot-based PP sales minus contract-based sales measured across the PP unit. When this differential provides a positive numerical output, this implies that spot-based PP sales derive a higher margin than contract-based sales. Similarly, when this differential provides a negative numerical output, this implies that spot-based PP sales derive a lower margin than contract-based sales.

SPOT vs. BUY SPOT/SELL DOMESTIC MARGIN This provides a weekly comparison of the calculated margin for spot-based PP sales measured across the PP unit versus the margin achieved by selling PP at domestic price using purchased spot propylene feedstock. This model assumes that the PP plant is located remote from the propylene supply. The ICIS Weekly Margin PP Europe report will provide the three above comparative data charts on a three-week rotational basis. The ICIS Weekly Margin PP Europe report will also provide a longer range view of integrated PP margins (naphtha) and integrated PP margins (PDH) on alternate weeks. READING THE CHARTS In the short-term charts and longer range margin view, the integrated margin is derived by reading the top of the wedge, the sum of the ethylene margin per tonne of PP (yellow) and the standalone PP margin (blue). Where the standalone margin is a loss (red), the integrated margin is read as the top of the yellow wedge or, where there is no yellow wedge, the bottom of the red. COMBINING PE AND PP MARGINS It should be noted that, to assess a petrochemical complex margin, for a petrochemical producer engaged in both the PE and PP businesses, requires looking at the integrated PE margin (from the ICIS Weekly Margin PE Europe report) and adding the standalone PP margin from this report. PUBLICATION FREQUENCY The ICIS Weekly Margin PP Europe report is produced on a Friday at the close of business in Europe and distributed to customers on the following Monday, subject to schedule planning. When the Monday is a public holiday in the UK, the report is distributed on the Tuesday. The report is not published on some public holidays. Holiday dates and days of publication may be subject to revision. From late September 2015, ICIS has also made available its margin series for download in Excel format. Each week subscribers are able to download from the ICIS dashboard the latest 12 months’ worth of weekly data for the calculated margins, the feedstock costs and, where applicable, the co-product credit values. Combined with relevant price history series, also available via ICIS dashboard, this allows subscribers to manipulate ICIS data more easily than was previously possible from the weekly pdf format.
